Key Differences in Using Environmental Test Chambers Between Summer and Winter

I. Core Difference Comparison Table

II. Season-Specific Precautions

(1) Summer Operation: Focus on High Temperature/High Humidity/Overload Prevention

1. Ambient Heat Dissipation Management

• Reserve ≥50cm ventilation space around the chamber; avoid direct sunlight or proximity to heat sources (e.g., workshop ovens, air conditioner outlets).
• Ensure laboratory air conditioning operates normally, maintaining room temperature at 25-30℃. If room temp exceeds 35℃, install industrial fans or cooling devices to assist heat dissipation and prevent refrigeration system overload protection triggered by high ambient temperatures.

2. Moisture & Condensation Control

• Regularly clean chamber door gaskets with a dry cloth to prevent sealant aging and air leakage caused by high humidity.
• After humidity tests, open the chamber door promptly for ventilation and wipe off condensation to avoid moisture damage to sensors (e.g., humidity sensors).

3. Equipment Operation Protection

• Avoid prolonged continuous operation of extreme low-temperature tests (e.g., below -40℃). Recommend shutting down for 1 hour after 8 hours of operation to protect the compressor.
• Periodically inspect refrigeration system radiators (condensers) and remove dust/debris (blow with compressed air monthly) to ensure heat dissipation efficiency.

(2) Winter Operation: Focus on Anti-Freezing/Low Humidity/Startup Failure Prevention

1. Ambient Temperature Guarantee

• Maintain laboratory temperature above 5℃ (strictly follow 10℃ if specified as the minimum operating temperature) to prevent pipeline freezing (e.g., refrigeration capillaries, humidification pipes).
• For unheated laboratories, install an insulation cover (with ventilation holes reserved) or activate the "preheating mode" (if supported) before testing.

2. Humidification System Maintenance

• Use distilled water in the humidification tank to avoid pipe blockage from impurity crystallization at low temperatures.
• Drain water from the humidification tank and pipelines during long-term non-use to prevent freezing-induced component damage.

3. Startup & Operation Specifications

• In low-temperature environments, activate "standby mode" for 30 minutes preheating before setting test parameters to avoid compressor burnout from excessive startup load.
• If startup fails (e.g., compressor inactivity), check power voltage (prone to instability during winter peak hours) or contact after-sales to inspect pipeline freezing.

4. Low Humidity Compensation

• For low-humidity tests (e.g., ≤30% RH), winter dryness may cause rapid humidity. Adjust humidification frequency appropriately and use the "humidity calibration" function to reduce fluctuations.

III. General Precautions (All Seasons)

1. Calibrate temperature/humidity sensors quarterly to ensure data accuracy.
2. Clean air filters monthly to maintain airflow circulation.
3. Arrange test samples evenly to avoid blocking internal air ducts and ensure temperature/humidity uniformity.
4. For long-term non-use: Run the chamber for 1 hour monthly in summer (moisture prevention) and drain pipeline water in winter (freezing prevention).
